[HIV-1 vaccination--is there hope?]

Area of Science:

• Immunology
• Virology
• Vaccinology

Context:

• The ongoing human immunodeficiency virus (HIV) pandemic affects 39.4 million people globally.
• Despite extensive research, an effective HIV vaccine remains elusive, with past Phase III trials failing to prevent transmission.
• Significant hurdles in developing an HIV vaccine include incomplete understanding of HIV pathogenesis and the virus's high mutation rate.

Purpose:

• To review distinct aspects of the immune response relevant to HIV vaccine development.
• To discuss current strategies and approaches for creating an effective HIV vaccine.

Summary:

• This review examines key immunological factors that could be leveraged for designing novel HIV vaccine strategies.
• It analyzes the challenges posed by HIV's complex pathogenesis and rapid evolution, which complicate vaccine design.
• Current vaccine approaches are discussed in light of these challenges and potential immune targets.

Impact:

• Provides a comprehensive overview of immunological targets for future HIV vaccine research.
• Highlights critical knowledge gaps in HIV pathogenesis and viral evolution impacting vaccine efficacy.
• Informs the direction of research for developing effective prophylactic or therapeutic HIV vaccines.
